3d Printed Part Sets - Freewing F-4D Phantom II

[apmech1]

I had to create them in autocad. I used dimensioned photos / diagrams. Once I post some pics, any feedback will be welcome.

[Dirty Dee]

Gotcha. Yea, I was very curious about source drawings since I have the BRU-41 and BRU-42 high on my to-do list for CADing up and printing. Working on LAU-117 and higher fidelity AGM-65s currently.

So in the videos about these parts we see a canopy mod, is that in the works from motion?

[apmech1]

My cad skills are pretty rusty, I wish I had drawings to go off of. I couldn't get the scale fidelity I wanted with the ejector racks for fear of weakness in the airflow. Here is what I have so far:

[Prowler901]

Well, I'd say those look dang good, apmech1! :Cool:

I've been working on pylons for the wing stations along with 370Gal drop tanks for the Freewing 70mm F-16. I hope to have them ready for folks to test out soon.

I am working on making the fuse for the nose of the bomb.

Looking good, apmech1.

Bbaumer, my canopy mod just shows the potentIal for people considering the ladder 3DPUP, which requires at least the front canopy to be cut open for the ladder to latch into the cockpit itself. I've heard of some people buying a spare canopy/cockpit to use as static display on the flight line. As for rigging a functioning, flight-safe canopy... industrious modelers will need to cut the canopy and frame it to keep everything rigid during opening and especially during flight. Ply, styrene, or 3DP ABS could work well here.

Nice apmech1,

One tip I can share from my modeling experience is that 1:1 modeling can make things easier when working off full scale drawings with dimensions, but sharp edges and small details may not properly translate when you scale down for 3dprinting. with typical nozzles being 0.4mm for hobby printers you will notice a degradation of detail on anything that starts to reach 0.4mm and smaller. The sway braces on your BRU-42 might not print properly if the diameter is too small, and the printer might just deposit small blobs rather than run circular perimeters when it reaches those details.

Don't want to derail this thread too much, but check out the 3DP thread for more discussion:

Cool, i will check that out, thanks for the tip! I will scale it down in cad and see how the print layout looks like.

So they are juat glued static Alpha?

Trying my hand at an AIM7 Sparrow for the underside, I'm a 2d Draftsman by trade, having to learn the modeling as I go.

I'll say this, a 1/11th scale sparrow is huge!

[Prowler901]

Those look great! And, just about the right scale for my FW F-16. :Cool:

If I get them to print well, I'll be happy to share the files, still working through things . I did get a test print of the tail nozzle looking fairly good and smooth




[EDIT] and here's the nose piece, now I just need some tubes and fins, both are pretty easy prints

[Prowler901]

Yeah, that looks pretty nice. :Cool:

[Dirty Dee]

The best part about modeling ordinance for the A-10 is there is a lot of overlap with the F-4. Here is an AN/ALQ-119 I made specifically for the hog, but can scale down and use on the phantom as well

[apmech1]

That looks awesome! What scale are you guys using for the F-4? I test printed an aim7 @ 1/11.59 scale. I dont have the plane to compare (yet mid-May ;) it to.

[apmech1]

my bad, I was using the wrong length for the full scale Phantom. the scale I am calculating now is1/12.389381.

My canopies are propped up for static display. I fly with a stock canopy/cover.

[Alpha]

Keep going on the Sparrow! I want to print a couple for the forward stations.

The sky really is the limit with this 3DP stuff.

[Prowler901]

WOW, Alpha! That's some beautiful work! :Cool:
